Seems there is a fatal error with this method of encryption - the same one as with TrueCrypt.  When you get a system update and the initrd file is replaced, the encryption information is lost.  Fortunately, I was still able to boot into the old kernel, and although there were some errors about a missing module now, I could at least get up and running and copy my data off to another system before having to rebuild.....

It could be worse.  I could have install Pointsec and rendered the system into a boat anchor.

If anyone has a good idea about how to migrate the encryption settings into the new initrd file, they would instantly become a "Linux god"... <LOL>
